Abstract (en)
[origin: EP0651502A1] The invention relates to an amplifier element with current mode differential structure, this amplifier element comprising: - means (21, 22) for generating a common-mode bias current; - a translinear multiplier (25) receiving, on two inputs (A, B), the said common-mode bias current and a differential-mode current to be amplified, and delivering, on two outputs (C, D), an amplified differential-mode current; - means (26) for biasing the said translinear multiplier (25) from the said bias current received by the said translinear multiplier; and - means (27) for compensation of the common-mode current on the said outputs (C, D) of the translinear multiplier. <IMAGE>
